HARROW.

Specification of Letters Patent.

Patented J an. 2, 1912.

Application led July 23, 1910. Serial No. 573,450.

To all whom it may concern:

Be it known that I, WILLIAM THoRN, a citizen of the United States,residing at Arnaudville, in the parish of St. Martin, State ofLouisiana, have invented certain new and useful Improvements in Harrows;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appert-ains to make and use the same.

This invention relates to harrows.

The object of the invention resides in the construction of a harrowparticularly adapted for use in cultivating cotton, which is providedwith means for removing the diseased forms or squares, caused by theboll weevil, from the cotton plant.

To this end the invention consists in the details of construction andthe arrangement and combination of parts to be hereinafter more fullydescribed and particularly pointed out in the appended claim.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views; and -in which,

Figure 1 is a side elevation of a harrow constructed in accordance withthe invention; Fig. 2, is a front view of'same; Fig. 3, a plan view ofthe harrow; and, Fig. 4, a section on the line 4-4 of Fig. 3.

Referring to the drawings, the harrow is shown as comprising a pair ofeonvergently disposedtoothed beams 10 and 11 connected together atopposite ends respectively by arched members 12 and 13. The archedmember 12 has its terminals bent outwardly and disposed upon the uppersides of the beams 11 and 10 respectively. A single bolt extends througheach of said beams and each of said outwardly bent terminals so that apivotal connection between each end of the arched member 12 and thebeams 11 and 10l is had. The arched member 13 has its terminals bentoutwardly as at 14 and 15 and disposed upon the upper sides of the beams11 and 10 respectively. The outwardly bent portion 14 is provided with aplurality of spaced apertures 16, while the outwardly bent portion 15 islikewise provided with a plurality of spaced apertures 17. Theseapertures 16 and 17 enable the beams 10 and 11 to be moved toward andaway from each other at the end adjacent the arched memi ber 13; saidbeams being secured in a desired adjusted position by bolts 18 passingthrough said beams and through the apertures `14 and 15. The archedmembers 12 and 13 are strengthened by means of mey tallic straps 19 and20, which straps also serve to assist in supporting handles 21 andVAnother chain 26 is hung from the arched member 13 by means of straps 27and 28. The strap 27 encircles both the arched member 13 and the handle22 while the strap 29 encircles both the arched member 13 and the handle21 such engagement between the straps 21 and 22 and handle holding theformer against longitudinal movement on the arched member 13. 'Ihestraps 23, 25, 27 and 28 are detachably mounted upon their respectivesupporting parts so that various lengths of chain may be disposedbetween straps engaging a given arched member.

In the cultivation of cotton t-he beams 10 and 11 are disposed onopposite sides of a row of cotton plants and during the movement of theharrow the chains 23 and 26 will engage the foliage of the plants andremove therefrom those portions which have been attacked by the bollweevil. It will be apparent that the chains 23 and 26 may be.

easily adjusted so as to properly operate upon vplants of diierentheights.

While the harrow has been described as particularly adapted for use inthe cultivation of cotton it will be obvious that same may be utilizedwith equal facility in cultivating plants of any type which are disposedinrows.

Having thus described the invention what is claimed as new is:

A harrow comprising a pair of spaced toothed beams, arched membersconnecting said beams at spaced points, bars connecting said archedmembers at spaced points and disposed respectively on opposite sides ofthe longitudinal axis of the harrow, handles secured to one of saidarched members and to said bars respectively, a pair of strapsencircling one of said arched members, each ioo having portions thereofdisposed Qn oppo-v each arched member respectively and dis- 10 sitesides of respective connections between posed between the beams.

said bars andv arched member whereby said In testimony whereof, I aiiiXmy signa straps are held against longitudinal moveture/in presence oftwo witnesses.
